获取mac地址的方法，关键是要那个头文件，其它比较简单。代码如下：/*begin*/#include "stdio.h"#include "stdlib.h"#include "windows.h"#include "Iphlpapi.h"#pragma comment(lib, "Iphlpapi.lib")#define & UNICODE&#define snprintf _snprintfbool GetLoaclMac(){&& &DWORD & & & & & &&& &DWORD & & & & & & adapterinfosize=0;&& &PIP_ADAPTER_INFO & &&& &PIP_ADAPTER_INFO & &pAdapter = NULL;&& &PIP_ADAPTER_INFO & &pNextAdapter = NULL;&& &&& &if((err=GetAdaptersInfo(NULL,&adapterinfosize))!=0)&& &{&& & & &if(err!=ERROR_BUFFER_OVERFLOW)&& & & &{&& & & & & &printf("GetAdapterInfo 大小错误: %d\n",GetLastError());&& & & & & &&& & & &}&& &}&& &&& &if((padapterinfo=(PIP_ADAPTER_INFO)GlobalAlloc(GPTR,adapterinfosize))==NULL)&& &{&& & & &printf("内存分配错误: %d\n",GetLastError());&& & & &&& &}&& &&& &if((err=GetAdaptersInfo(padapterinfo,&adapterinfosize))!=0)&& &{&& & & &printf("GetAdaptersInfo 错误: %d\n",GetLastError());&& & & &GlobalFree(padapterinfo);&& & & &&& &}&& &pNextAdapter =&& &pAdapter = pNextA&& &bool FindRealAdapter = char *macaddr[10]; char temp[100];&& &for (int i = 1;pNextAi++)&& &{&& & & &pAdapter = pNextA&& & & &pNextAdapter = pNextAdapter->N&& & & &printf("找到网卡: %s\n", pAdapter->Description);&& & & &BYTE* hostmac = pAdapter->A&& & & // printf("网卡地址: %.2X-%.2X-%.2X-%.2X-%.2X-%.2X\n",&& & & & &//hostmac[0],hostmac[1],hostmac[2],hostmac[3],hostmac[4],hostmac[5]);
snprintf(temp,sizeof(temp),"%.2X-%.2X-%.2X-%.2X-%.2X-%.2X",hostmac[0],hostmac[1],
hostmac[2],hostmac[3],hostmac[4],hostmac[5]); // memcpy(macaddr[i],temp,sizeof(macaddr[i]));
//memset(temp,'\0',sizeof(temp));
printf("网卡地址:%s\n",temp);
}&& &GlobalFree(padapterinfo);&& &}void main(){
GetLoaclMac();}附件为所程序所需要的库文件，拷到对应的include和lib目录即可。
